Day 1 - Agnew Meadows to Ediza Lake To start, you catch a shuttle from Mammoth Mountain Ski Resort (it's the only way to get to the start of the walk; you park your car near the bus stop) and then set out on the River Trail from Agnew Meadows. I came across an old-timer doing the whole PCT…his trail name was Finder. He finds things that people have lost!
I then hiked down into a canyon to Olaine Lake and up to
Shadow Lake and the John Muir Trail.
After a swim in Shadow Creek and some lunch on a rock in my undies I climbed up to
Ediza Lake. All the advice says to camp near the west side of the lake (per national forest restrictions), but the bugs are bad in Summer. So I camped off the trail on the way up to Ediza and did an extension to
Iceberg Lake. I found a beautiful spot beside a rocky outcrop where I made tea and dinner wtih a view of the snow-peaked mountains.
Day 2 - Ediza Lake to Thousand Island Lake
The next day I walked back down to the John Muir Tail and took the trail north over a high pass to
Garnet Lake. And then up and over to two smaller lakes, Ruby Lake and Emerald Lake, which were both stunning. Then a final climb to reach the outlet of
Thousand Island Lake where John Muir Trail is joined by Pacific Crest Trail.
I took the trail along the north shore of the lake (far less mosses than on the south side) to find a place to camp (at least a quarter mile from the outlet, per regulations). I camped here and overnight there was a massive avalanche on the other side of the lake.
Day 3 - Thousand Island Lake to Agnew Meadows
In the morning I took the High Trail out from Thousand Island Lake and crossed a bunch of slopes on the northeast side of a broad canyon to return to Agnew Meadows where you can catch a bus back to your car.
